IMPROVEMENT IN HUBS FOR CARRIAGE-WHEELS.

Specification forming part of Letters Patent No. 122,322, dated Janna-ry 2, 1872.

To all whom it may concern:

Be it known that l, J AGCB KRITGH, of Cleveland, inthe county of'Cuyahoga and State of Ohio,haveinven ted acertain new and ImprovedCarriage-Wheel 5 and I do hereby declare that the following is a full,clear, and complete description thereof, reference being had to theaccompanyin g drawing making part of the same.

SPECIFICATION.

ridge-wheel hub, and the special object of said invention is to providea neat, simple, and secure way of fastening the wheel to the axle bymeans of a circular plate fitted to and in contact with the posteriorside of the collar of the Iaxle, 'and which plate is then bolted to aiiange on the inner end of the, hub, a more full and completedescription of which is as follows:-

The hub referred to consists, in part,'of two sections, A B, Fig. 2,each of which has a wide flan ge, O, between which the base of thespokes D are litted in mortises cut in the wooden core Etted snugly tothe inside of the two sections, as shown in Fig. 3, in which a shows thetenons itted in the wooden core. The sections A B are'secured to eachother and to the sides of the spokes by bolts or rivets b, whereby saidspokes are ystronglybraced in a lateral direction. F, Figs. 3 and 6, isthe axle-box in which the axle or spindle G is fitted. H is theaxlecollar. l is the enlargement before the collar and J the enlargementbehind the collar. The enlargement I is fitted in the axle-loox, whereasthe enlargement J is fitted in the circular plate K. It will be observedthat said plate is provided with a rim or narrow iiange, K Fig. 5, onits inner side, whereby is formed a recess, k, in which is fitted halfthe thickness of the leather washer O. It will also be seenthat sec.

tion or thimble B is provided with a flange, L, Fig. 3, and that aroundthe edge of said iiange is a rim, B', whereby is formed a recess, b,Fig.

c, in which is r11-.ted the other naif tte thieknessof the leatherwasher 0. In the bottom of said recess is fitted the collar H oftheaxle, so that the posterior side thereof is iiushed with the face of theliange-L or bottom ofthe recess b, in which the washer 0 is fitted. iThe plate K,when adjusted to the `iian ge L, forms therewith a chamberin which is contained a washer, O, referred to, which lits closely butnot tightly both the side ofthe collar and the bottom of the recess b,`and also the face or bottom of the recess in the plate K, and which issecured to the flange L by bolts c or their equivalents. The purpose ofthe vwasher 0 interposed between the side of the collar and the plate Kis to prevent the two m etal surfaces from contact and thereby protectthem from frictional wearing, and also to prevent them from rattling.Between the anterior face of the collar and the end of. the axle-box inwhich it is iitted is interposed a leather ring or washer for a similarpurpose.` From the above description and illustration it will be seenthat the hub or wheel is retained upon the axle by means of the plate K,being bolted or otherwise secured to the flange L, forming a part of thehub, which7 being on the anterior side ofthe collar and the plate on theopposite side, renders it impossible for the wheel to come oil' from theaxle, unless the bolts c are first removed, thereby detaching the platefrom the hub.

By this means a simple, neat, and secure connection is made of the wheelto the axle, and which can be easily and readily removed therefrom foroiling or for other purposes by simply removing the bolts c, which willallow the wheel to slip from the spindle or axle. This manner ofsecuring the wheel to the axle effectually excl'udes dirt and dust fromthe axle-box; hence the wheel will run smoothly and with but littlefrictional wearing. It will be observed that the end of the spindle ishollow, the purpose of which is to hold oil or grease in reserve, fromwhich the spindle is self-supplied, and that in the side of the axle iscut a` groove, c, Fig. 4,

for conducting the oil along the spindle, said groove havin g acommunication with the chamber inthe endof the axle by'means of a small4hole, f, Fig, 4. lt will be observed thatthe bolts c, whereby the plateis connected to the flange of the hub, also pass through the washer O;

hence, said .washer is held securely inplace.

The collar H is of large diameter, whereby is obtained more strength andendurance to the A attachment of the Wheel to the axle, as the largesize ofthe Collar more effectual] y pre vents twisting or wrenching ofthe Wheel on the axle than a collar of small diameter; hen'ee the WheelWill run with more steadi ness and With less frictional Wear than if thecollar were of small diameter, as they usually are in this class ofhubs.

C lafims.

lewithin said rim, flange L forming part of the thimble or ysee-tionAand provided with a rim, B', and recess b', as arranged in relation tothe Washer 0, axle Gr, as applied to a Wooden hub y conjointly,substantially as and for the purpose set forth.

2. The Wheel seouredto the axle by means of the plate K arranged on theposterior side of the collar H and connected to the lian-ge L of the hubby screw-bolts or their equivalents with the collar H in the chamber ofthe llange L, as applied to Wooden hubs, in the manner and for thepurpose substantially as set forth. 3. The circular plate K incombination with the flange L when said flange forms a part of thethimble or sentieri A, all arranged in combination With a Wooden hub,substantially in the manner as described, and for the purpose set forth.
